Hi,

This DVD/VCR combo came in dead. Trouble was IC101 blown in the PSU
circuit, an ICE2B265 SMPS control IC, and C108 - 33uF, 25V - was
bulging and leaking.

All worked fine after replacement parts inserted, but at one point the
AV channel on the TV set started flicking rapidly between AV and the
last channel it had been on, as though the control voltage telling the
set that a SCART device was connected was switching on and off. I
thought maybe the SCART had some bad joints, so I took the tape deck
out and then the mainboard beneath it. No bad joints and problem has
not since recurred.

Trouble is, since I did that - although i have checked for dry-joints
and cable contacts being clean and correctly inserted, etc. - it won't
play DVD discs properly, although tape deck operation is fine.

Upon insertation of the DVD, it goes to the language selection screen
as usual, and after selection, it gives the copyright notice. At this
point it should now show the silly nonsense logo of the film creator
and eventually take you to the proper DVD menu from where you can then
select to play the film. But, it's not doing this. Right after the
copyright notice, it goes to the screen which comes up when 'stop' is
pressed. In fact, it actually shows the stop/pause icons (this is
normal for one press of stop. A second press causes just the stop icon
to appear and you can now no longer press play again and return to
where you were in the film) and if you press play, it tries to for a
second but then shows the stop/pause icon again, as though you
immediately pressed stop after pressing play.

Incidentally, this is all being done by the remote, but I have ruled
the remote out of the equation completely and satisfactorily. I can't
use the actual panel buttons as some kind of child-lock is on and if
the buttons are pressed, the display simply shows 'Safe' for a few
moments. I haven't got the original remote so can't turn child-lock
off. Only the front panel eject buttons and stop button for the DVD and
tape deck work whilst this lock is on.

The fault seems to be worse at times, reacting as though the stop
button has been pressed twice (only stop icon shows on the screen). No
heating or pressing of the PCB affects this fault, though. If I press
'play' on the remote, however, when it's reverted by itself to
stop/pause mode, and keep the button pressed, the disc will play as
usual, until the moment I stop pressing the play button, whereupon it
reacts as though the stop button is still being pressed.

I'm puzzled and I cannot find anything like this fault for any DVD or
DVD VCR combo, and no service manual!

Someone please help and I'd be very appreciative,

Many thanks,
James



I mused for a second with the thought that maybe you need to set the region code of the DVD player again for one reason or another. I now figure this unlikely because any DVD player should ask the user to set the region code if it does not find it. However you may want to check how to set the region code.

On the other hand your story so far definitely jives with a bad PSU; there is relatively little CPU usage or reading of the disc to display still images such as FBI warnings, but one would expect a lot more activity for loading a menu or a movie.
